of Delaware Pittsburgh, Pa., assignor to M. H. Detrick Company, Chicago, 111.,

a corporation Application August 18, 1948, SerialNo. 44,842 2 Claims. (Cl. 110-99) a consideration of the accompanying drawing,-

constituting a part hereof, in which like reference characters designate like parts, and in which Fig. 1 is a view in perspective partially in cross section of a suspended arch and hanger brick embodying the principles of this invention;

Fig. 2 a view in perspective of a refractory hanger;

Fig. 3 a similar view of a half-section of a face tile for use with the hanger shown in Fig. 2; and

Fig. an end elevational View of a hanger brick and face tile assembly mounted on an arch support.

In the drawing the numeral l designates a beam from which is suspended channels or arches 2 which are clamped to the beam by suitable clamping brackets 3. The metallic elements I and 2 may be designated a suspended arch which support hanger brick 4 and face or tile brick 5 and 6, the hanger brick and tile combination being especially designed to provide a maximum area of surface insulation designated by the reference numeral '1.

The hanger brick 4, as shown in Fig. 2, are provided with deep notches or grooves 8 which are engaged by the legs of oppositely disposed channels 2 by which they are suspended as shown in Fig. 1. The lower ends of the hanger bricks are provided with grooves 9 and keys H! which interact and interlock with tongues H and notches [2, respectively, of the face tile sockets shown in Fig. 3. The notches or grooves 9 of the hanger brick form a tongue H at the bottom of the hanger brick which is disposed in the peripheral groove 14 of the face tile 5, Fig. 3. The faces of the tongues and grooves of the hanger brick and tile may be slightly chamfered as shown in Figs. 2 and 3.

As shown in Fig. 4, the face tile 5 are assembled on the hanger brick 4 by bringing them together with their juxtaposed faces forming a joint l5 at substantially the center of the hanger brick 4, Fig. 4. As shown in dotted lines in Fig. 4, adjacent face tile 5 suspended from hanger brick 4 contact to form a continuous suspended roof, and the spacing between the arch members 2 supporting the hanger bricks 4 is such that face tile 6 are supported on shoulders 16 of the face tile 5, forming what is known as a ship joint.

As is apparent from the several figures of the drawing, the hanger brick and face tile with the intermediate tile 6 are interlocking when assembled and sections thereof are readily replaced when damaged or worn. As appears from Fig. 1 of the drawing, the surface insulation 1, which may be of sheet or granular form, covers substantially the entire area of the refractory tile and protects the metal structure from intense heat. It is to be noted further that all of the metal parts I and 2 are above the refractory material and above the surface insulation I.

The thickness of the surface insulation 1 is determined by the space between the supporting channels 2 and the top of the face tile 5 and 6. This distance may be varied by varying the spacing of the notches 8 and 9 more or less to increase the depth from the bottom of the channel to the top of the face tile as seen in Fig. l of the drawing.

By eliminating the embedment of the metal parts in the refractory material, the arches do not burn out and the life of the suspended arch is greatly increased. Also by providing the interlock design of hanger brick 4 and face tile 5 the latter can be readily assembled and suspended from the arches without the interlocking parts being displaced.

Although one embodiment of the invention has been herein illustrated and described, it will be apparent to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

1. In a furnace arch, metal suspending members, refractory hanger members having flat end faces and opposite flat side faces and having upper grooves extending continuously across said end faces and opening into said opposite side faces for slidable engagement of said hanger members with said metal members, said hanger members having lower horizontally elongated grooves extending continuously across said end faces adjacent the lower ends of said hanger members and having horizontally elongated grooves in said side faces in alignment with and extending from said lower grooves, vertical ribs extending across said grooves in said side faces, and a pair of facing tiles suspended from and embracing the lower ends of each of said hanger members, each of said tiles having flat side faces and each having a recess therein extending through one of said flat side faces and the top face thereof, said recess having undercut side and end walls providing horizontal tongues and grooves in said walls of each recess, the tongues on said recess side walls having notches therein, said lower grooves receiving the tongues on the recess end walls of said pair of tiles and the grooves in the side walls of. said hanger members receiving the tongues in the recess side walls of said pair of tiles with said ribs seated in said notches.

2. A refractory hanger member having 2, rectangular body portion having fiat end faces and fiat side faces, said flat end faces each having an upper groove extending continuously across the same and opening into said opposite side faces to slidably suspend the same from supporting means, and each end face having a lower horizontally References Cited in the file of this patent UNITED STATES PATENTS Number Name Date 1,623,632 McCaig Apr. 5, 1927 1,710,247 Stevens Apr. 23, 1929 1,711,822 Abbott May 7, 1929 $446,766 Hosbein Aug. 10, 1948
